Hermes Agent 0.21.6 released
A patch release bundling approximately 2,100 merged pull requests and 3,027 closed issues since v0.21.5, with security fixes for dashboard authentication, git filters, and email headers.
What changed in 0.21.6
- Dashboard authentication now validates X-Forwarded-For headers, limits auth audit log writes, enforces request-body size limits, and restricts native sign-in redirects to loopback addresses.
- Git filter programs in untrusted repositories no longer run automatically during session snapshots, subagent worktrees, kanban operations, or workspace cleanup.
- Email gateway sender validation now rejects spoofed display names in From headers that could bypass the allowlist.
